This bar chart visualizes total BMW sales volume by region (Asia, Europe, North America, etc.) from 2010 to 2024, using aggregated data from a CSV file. The visualization employs D3.js v7 with an SVG rendering approach, using `scaleBand` and `scaleLinear` for axes and data mapping. The `join()` API builds the bars, while `axisBottom` and `axisLeft` generate the labeled axes. Data parsing uses `csvParse` with `autoType` to infer column types.
